(EN) This finned tube heat exchanger (100) is provided with: a plurality of fins (31) arranged in parallel; and a heat transfer tube (21) configured in a manner so that a medium that exchanges heat with air flows therewithin. The fins (31) are corrugated fins formed in a manner so that a hill section (34) appears in at least one position in the direction of airflow, and include: a tube periphery section (35 or 37) formed at the periphery of the heat transfer tube (21); a first inclined section (38) tilted with respect to the direction of airflow in a manner so as to form the hill section (34); a second inclined section (39) connecting the tube periphery section (35) and the first inclined section (38) to each other; and a slit (23) formed in the second inclined section (39).
